The Jhanjra coal block covering a surface area of 11.50 km 2, spread across 8 extractable seems, has a total reserve of about 200 million tonnes of coal. Development of this mine was initiated in the 1980s. While open-cast mining is cheaper and less labour-intensive, it is much less environment friendly compared to underground mining.
an underground coal mine. 2. Experimental Investigation To monitor DPM concentration near a man-riding vehicle, field experiments were conducted in one of the eight working seams of an Indian coal mine [6]. To ensure that the intake air was free of DPM, the experiment was conducted in an isolated intake airway (mine gallery).
The underground infotainment area at Saoner is as huge as around 5 sq km (see box). "Here, a unique man-riding system takes you down deep," said an MTDC official from Nagpur. Since, Gondegaon is an open cast mine, it can be seen from above. "To operate this tour, there should be at least 10 passengers.
